Answer

Is this study:

QuaNtitative (collection, analysis, and reporting of numerical data)
Measurable data (how many; how much; or how often) used to formulate facts, uncover patterns in research, and generalize results from a larger sample population; provides observed effects of a program, problem, or condition, measured precisely, rather than through researcher interpretation of data. Common methods are surveys, face-to-face structured interviews, observations, and reviews of records or documents. Statistical tests are used in data analysis.

Go to Section I: QuaNtitative

QuaLitative (collection, analysis, and reporting of narrative data)
Rich narrative documents are used for uncovering themes; describes a problem or condition from the point of view of those experiencing it. Common methods are focus groups, individual interviews (unstructured or semi structured), and participation/observations. Sample sizes are small and are determined when data saturation is achieved. Data saturation is reached when the researcher identifies that no new themes emerge and redundancy is occurring. Synthesis is used in data analysis. Often a starting point for studies when little research exists; may use results to design empirical studies. The researcher describes, analyzes, and interprets reports, descriptions, and observations from participants.

Go to Section II: QuaLitative

Mixed methods (results reported both numerically and narratively)
Both quaNtitative and quaLitative methods are used in the study design. Using both approaches, in combination, provides a better understanding of research problems than using either approach alone. Sample sizes vary based on methods used. Data collection involves collecting and analyzing both quaNtitative and quaLitative data in a single study or series of studies. Interpretation is continual and can influence stages in the research process.

Section I: QuaNtitative
Level of Evidence (Study Design)
Is this a report of a single research study?	□ Yes	□ No Go to B
1. Was there manipulation of an independent variable?	□ Yes	□ No
2. Was there a control group?	□ Yes	□ No
3. Were study participants randomly assigned to the intervention and control groups?	□ Yes	□ No
If Yes to questions 1, 2, and 3, this is a randomized controlled trial (RCT) or experimental study.		LEVEL I
If Yes to questions 1 and 2 and No to question 3 or Yes to question 1 and No to questions 2 and 3, this is quasi-experimental. (Some degree of investigator control, some manipulation of an independent variable, lacks random assignment to groups, and may have a control group).		LEVEL II
If No to questions 1, 2, and 3, this is nonexperimental. (No manipulation of independent variable; can be descriptive, comparative, or correlational; often uses secondary data).		LEVEL III

Section I: QuaNtitative (continued)
Is this a summary of multiple sources of research evidence?	□ Yes Continue	□ No Use Appendix F
1. Does it employ a comprehensive search strategy and rigorous appraisal method? If this study includes research, nonresearch, and experiential evidence, it is an integrative review (see Appendix F).	□ Yes Continue	□ No Use Appendix F
2. For systematic reviews and systematic reviews with meta-analysis (see descriptions below):
a. Are all studies included RCTs?		LEVEL I
b. Are the studies a combination of RCTs and quasi-experimental, or quasi-experimental only?		LEVEL II
c. Are the studies a combination of RCTs, quasi-experimental, and nonexperimental, or non- experimental only?		LEVEL III
A systematic review employs a search strategy and a rigorous appraisal method, but does not generate an effect size. A meta-analysis, or systematic review with meta-analysis, combines and analyzes results from studies to generate a new statistic: the effect size.

Complete the Quality Rating for QuaLititative Studies section (below)

Quality Rating for QuaLitative Studies

Circle the appropriate quality rating below:

No commonly agreed-on principles exist for judging the quality of quaLitative studies. It is a subjective process based on the extent to which study data contributes to synthesis and how much information is known about the researchers’ efforts to meet the appraisal criteria.

For meta-synthesis, there is preliminary agreement that quality assessments should be made before synthesis to screen out poor-quality studies¹.

A/B High/Good quality is used for single studies and meta-syntheses².

The report discusses efforts to enhance or evaluate the quality of the data and the overall inquiry in sufficient detail; and it describes the specific techniques used to enhance the quality of the inquiry.

Evidence of some or all of the following is found in the report:

· Transparency: Describes how information was documented to justify decisions, how data were reviewed by others, and how themes and categories were formulated.

· Diligence: Reads and rereads data to check interpretations; seeks opportunity to find multiple sources to corroborate evidence.

· Verification: The process of checking, confirming, and ensuring methodologic coherence.

· Self-reflection and self-scrutiny: Being continuously aware of how a researcher’s experiences, background, or prejudices might shape and bias analysis and interpretations.

· Participant-driven inquiry: Participants shape the scope and breadth of questions; analysis and interpretation give voice to those who participated.

· Insightful interpretation: Data and knowledge are linked in meaningful ways to relevant literature.

C Lower-quality studies contribute little to the overall review of findings and have few, if any, of the features listed for High/Good quality.

Section III: Mixed Methods
Level of Evidence (Study Design)
You will need to appraise both the quaNtitative and quaLitative parts of the study independently, before appraising the study in its entirety.
1. Evaluate the quaNitative part of the study using Section I.	Level	Quality
Insert here the level of evidence and overall quality for this part:
2. Evaluate the quaLitative part of the study using Section II.	Level	Quality
Insert here the level of evidence and overall quality for this part:
3. To determine the level of evidence, circle the appropriate study design:
· Explanatory sequential designs collect quaNtitative data first, followed by the quaLitative data; and their purpose is to explain quaNtitative results using quaLitative findings. The level is determined based on the level of the quaNtitative part. · Exploratory sequential designs collect quaLitative data first, followed by the quaNtitative data; and their purpose is to explain quaLitative findings using the quaNtitative results. The level is determined based on the level of the quaLitative part, and it is always Level III. · Convergent parallel designs collect the quaLitative and quaNtitative data concurrently for the purpose of providing a more complete understanding of a phenomenon by merging both datasets. These designs are Level III. · Multiphasic designs collect quaLitative and quaNtitative data over more than one phase, with each phase informing the next phase. These designs are Level III.
